Abstract: An approach for providing setpoint optimization for air handling units. An area for such optimization may incorporate choosing a thermal comfort level index, finding a zone air properties target area and computing a supply air properties target area. Beyond the present approach, an outdoor air portion may be optimized, a feasible psychrometric path found, supply airflow versus temperature optimized, and a controller run to meet setpoints.

Abstract: An HVAC sensor is provided that includes a housing that houses a sensor. In some instances, a conduit is provided that has a first end that extends out the back of the HVAC sensor housing and adjacent to (and sometimes through) a hole in a duct of the HVAC system that is situated behind the HVAC sensor. The sensor itself may be positioned adjacent the other end of the conduit outside of the duct, and sometimes inside the housing of the HVAC sensor. The conduit may direct pressurized air emanating from the hole in the duct toward the sensor, thereby allowing the sensor to sense a parameter of the air in the duct without actually positioning the sensor within the duct.

Abstract: An energy-reducing method and apparatus for retrofitting a constant volume HVAC system, with or without an economizer, that provides heating, cooling, and ventilation to occupants within a building space. The present invention includes the introduction of a programmable logic controller and variable frequency drive (VFD) that takes control of the existing fan, heating, cooling, and optional economizer operation. The controller is programmed for the reduction of fan speed in the heating and cooling modes. The reduction of the fan speed in the ventilation mode when the 100% operation is not needed saves significant energy of the existing constant volume HVAC system where the fan motor is designed to run 100% of the time. The fan speed may be further reduced upon a reduction in sensed occupancy levels of the space, such as with a CO2 sensor. Additionally, the fan speed may be reduced in the heating and/or cooling mode to further reduce energy consumption. The controller may also be programmed and equipped with sensors to allow simultaneous mechanical compressor cooling and economizer free cooling operation, for the operation of the economizer in response to the monitoring of outside air and return air to determine the preferred source for cooling operations, to keep the outside air damper closed during the unoccupied heating modes such as morning warm-up, and/or to provide fault detection. The retrofit method and apparatus may be employed in a stand-alone or networked version.

Abstract: An energy saving air quality control system modulates supply fan speed by use of controlled, variable-frequency drive controls for automatic dampers or suction pressure to maintain adequate air flow across the evaporator coil at partial cooling loads. Demand ventilation in the system balances air quality and energy consumption by controlling the outdoor air damper in response to indoor CO2 levels. The control system variously either (1) produces a variable 0-10 VDC output signal to modulate the outside ventilation air damper as required to keep the CO2 concentration below a set point; (2) produces a 0 or 24 VAC signal to either open or close a two-position outside air damper for as long a time period as is required in order to keep the CO2 concentration below a set point; or (3) allows manually setting the outside air damper to provide proper ventilation air at maximum occupancy and maximum air flow and modulates the supply fan speed as required to keep the CO2 concentration as measured by a CO2 monitor below set point.

Abstract: The invention describes an outlet system in which a characteristic of one of gas and/or a liquid, for example the percentage CO2 in air, is measured in a central outlet duct (2). The outlet system comprises local outlet ducts (5, 6, 7) that are in flow communication with the central outlet duct (2). The flow through the local outlet ducts is partly determined by corresponding flow regulators (25, 26, 27) By means of selective setting of these flow regulators by a control system (22) the local value of the characteristic can be calculated using measured values in the central outlet duct (2) and the positions of the flow regulators (25, 26, 27). By means of the invention costs of sensor controlled ventilation systems, in, for example, residential and utility building, are reduced.

Abstract: A fresh air controller interfaces directly with the electromechanical circuit of an air-conditioner to control its operating settings based upon detected Carbon Dioxide (CO2) level in Parts-Per-Million (PPM) using a “Capno-Switch” which is in essence a specially designed single-beam NDIR CO2 sensor enhanced with features and specifications to render it rugged, compact and very low-cost; unlike conventional single-beam NDIR CO2 sensors, the “Capno-Switch” is capable of providing long-term stability and accuracy in CO2 measurements. The operating settings it can control for the air-conditioner include 1) shutting off the fan, cooling unit and fresh air damper to save energy when the detected CO2 level in the cold air duct is less than 600 PPM; 2) turning on only the fan when the CO2 level is between 600-1,000 PPM; 3) turning on both the fan and the cooling unit when the CO2 level is between 1,000-2,000 PPM and 4) starting to open the fresh air damper to let fresh air in when the CO2 level is in excess of 2,000 PPM. With the incorporation of the “Capno-Switch” as a fresh air controller, air-conditioners can now provide good indoor air quality while at the same time save energy by effectively shutting itself down when nobody is detected to be present.
